I MACHINE-F011 REMOVING PULP FROM cocoa AND OTHER PULPY BERBIES.

Specification of Letters Patent. Application filed June 16,1913. Serial No. 774,007.

Patented Sept. 8, 1914.

To all whom it may concern.

Be it known that I, J osii MAROELINO U1:- GnLLns, a citizen of the United States, and a resident of Baracoa, Cuba, Vest Indies, have invented a new and improved Machine for Removing Pulp from- Cocoa and other Pulpy Berries, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved machine for removing pulp from cocoa and other similar pulpy berries in a very siin 1e and economical manner and without in ury to the berries. In order to accomplish the desired result use is made of a series of drums arranged one exit ends arranged alternately on opposite sides of the machine, inlet end of the uppermost drum, chutes connecting the exit end of one drum with the inlet end of the next drum below, revoluble feeding members arranged in the said drums and rubbing and feeding members arranged in the said drums alternately with the said feeding members. Use is also made of means whereby the berries are retarded in the drums to insure a thorough rubbing aca view to separate the pulp from the berries.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the machine for removing the pulp from pulpy berries; Fig. 2 is a cross section of the same on the line 2-2 of Fig. 1; Fig. 3. is an enlarged side elevation of one of the feeding members and one of the adjacent rubbing members on the same shaft, the rubbing member having each spiral blade divided radially from the hub to the peripheral edge of the member; and Fig. i is a similar view of the feeding member and the rubbing and feeding member having spiral blades each located one below the other with a fourth lowermost drum E located a distance below the drum D and fixed within a washing tank F The uppermost drum B is proa feed hopper at the vided at the right-hand end with an inlet B connected with a hopper G containing the berries to be treated, and the left-hand end of the drum B is provided at its bottom with an outlet B opening into a chute H leading to an inlet C in the left-hand end of the drum C, which latter is provided at itsright-hand end with an outlet C connected by a chute H with an inlet D on the right-hand end of the drum D. The lefthand end of the drum D is provided with an outlet D? connected by a chute H with the inlet E of the drum E, whichlatter is provided at the right-hand end with an outlet E opening into the tank F opposite an elevator I for carrying the berries out of the tank F to a chute 1 arranged outside ofthe v tank F and delivering the berries to a basket or other receptacle held on the lower end of the chute I. 1

Centrally through the drum B extends a shaft J frame A, and on this shaft J are secured feeding members K and rubbing and feeding members L, L, of which the feeding members K are each provided with a hub K and spiral blades K having uninterrupted faces, as plainly indicatedin Figs. 3 and 4:. The hub K is secured by a set'screw K' or other suitable fastening means to the shaft J. Each of the rubbing and feeding members L is in journaled in suitable hearings on the disposed fadially and the form of a wheel and is provided with a hub L and spiral blades L each of which is divided radially from the hub L to the peripheral face of the blades so as to form a number of separate arms or pins spaced from: each other and with the edges of adj acent members parallel so that each arm is fan-shaped, that is, each face is narrower at the hub L than at the peripheral edge. A set screw L screws in the hubL against the shaft J to.secure the rubbingand feeding member in position on the shaft J between the feeding members K. By theme of the set screws K, L, the men'ibersv K and L can be adjusted relative to each otherso that more or less of a passage is formed between the corresponding blades K and L? with a view to feed the berries slower and cause more rubbing thereof, or to feed the berries faster and to reduce the rubbing action according to the nature of the berries under treatment. Thus for berries with a very tenacious pulp the passage is reduced to feed the berries slower and to cause more rub bing, and with berries having a less tena- Each rubbing and feeding member ,L"

(see Fig. 4) consists of a hub L provided with spiral blades L disposed radially and divided radially from the peripheral face to within a distance of the hub L so as to provide each blade with a solid portion adjacent the hub, and arms or pins extending radially outward from the said solid portion, as will be readily understood by reference to Fig. 4. It will be noticed in this case that the arms or pins of the blades L are considerably shorter than the arms or pins of the blades L of the rubbing and feeding members L. A set screw L serves to fasten the member L to the shaft J between a pair of feeding members K. As shown in Fig. 4:, for instance, the passage adjacent the ends of the blades K, L is very narrow, while the passage shown in Fig. 3, is wider, that is, the adjacent ends of the-blades K and L are spaced farther apart. By the arrangement described each rubbing and feeding member L alternates with a feeding member K, and each rubbing and "feeding member L likewise alternates with a feeing member K, and the members L and L are alternately arranged one relative to the other throughout the length of the drum B. The

feeding members K are arranged adjacent the inlet B and the outlet B and the outlet 1% is controlled by a retarding block N. mounted to slide on the shaft J and pressed on by a spring N" so as to push the retard .ing member N toward the last feeding member K. Now it' will be noticed that when the shaft J is rotated and with it the members K, L and L .and berries pass into the inlet B from the hopper" G. then such berries are correctlyfed from the right to the left in the drum B, and during this travel are caused to rub one against the other and against the blades of the feeding members K and those of the rubbing and feeding members L, L to loosen the pulp from the berries and also to detach some of the pulp from the berries. The drum B is perforated to; allow the loose, detached pulp to pass out through the perforations and to drop onto a chute O for carrying the pulp to one side of the-machine. The berries and; pulp remaining in the drumBv finally reach the retarding. block N, which is pushed by the advancing berries to the left to allow the berries to pass through the outlet B into the chute H, which delivers the berries to the inlet C of the next drum C. This drum 0 is provided with a centrally-disposed shaft feeding members K and the rubbing and feeding members L and' L, the same as above described relative to the drum B so vided with the feedingv onto the chute O berriesonto the elevator ed byib'eltwith J on which are secured the nu ist that further description of the same is not deemed necessary. A retarding member N x similar to the member N is arranged in the right-handendof thedrum C and is pressed on by a spring N to control the outlet C of the drum C. The drum C is non-perforate, and when the machine is in use water is poured into the inlet C in sufiicient quantity to aid in the separation of the pulp from the berries during. their travel from the left to the right in the drum C, the water also rendering the pulp more watery and thinner. The berries and pulpfinally pass through the outlet C and the chute LT into the inlet D of the drum D, which latter is provided with a centrally-disposed shaft J 2 journaled on the main frame Ayand promembers K and the rubbing and feeding, members L, L, the

same as above described relative to the drums B and-C. A retarding member'N is arranged on the left-hand end of the drum D, and is pressed on by a, spring N and the controls the outlet D retarding member N leading to the Jchute H perforated for the passageo pulp separated fromvcthe'berries, it-bein'g understood that the same action takes'place in the drum D as above described relative to the drums .B and Cyso that the pulp is practically all removed from the berries, and a large portion through the perforations of, the'drum The drum D is to one side of the machine The berrries next pass from the drum lD-into the drum E by way of the chute H and in this drum E is centrally arranged a shaft J provided with feedingfmembers K and rubbing and feeding members L, L, the

same as above described relativeto the, drums B,@ and D, Aretarding member N pressed on by a. spring N is arranged f on the right hand endof the drum-E and-"controls the outlet E throughiwhich drop the T. to be carriedbutwhich delivers the pulp f the water and.

of the plup passes and the inlet E,

of thejtank F as before mentioned. ZThef drum E is perforate and is submerged'in the water in the tank lB so that a washing r f to completely remove all traces of pulp from. i i 5 v to allow: the'pulp to ass through the perforations into the tan F to settle to the'bott'om thereof? and rubbing action is'given to the berries the berries and" In order to impart the desired motion to the shafts-J, J7, J5 and J ,-use,is"made ofa parting a rotary motionqto the shaft JY -afnd the members Land "L sec'uited on the said pulley} [secured on the shafttl and connect" 1 1 other machinery for m shaft. On the left-hand end of the shaft J is secured .a sprocket wheel by a sprocket chainQ with a s Q attached to the shaft J, so t at when the shaft J is rotated a like rotarymotion is Q connected rocket wheel) shaft so that when the shaft J 2 is rotated a like rotary motion is given to thefsliaft J 3 and the members K, L and Lsecured thereon. On the shaft J adjacent the sprgcket wheel B is secured a pulleyR connected by a crossed belt B with a pulley B secured on the left-hand end of the shaft J to rotate the latter when the machine is running. On the right-hand end of the shaft J 3 is secured a sprocket wheel S connected by a sprocket chain s'sith asprocket wheel S secured on the shaft 1 of thef'eiidless bucket elevator I to cause the buckets to travel and take up the berries when the ma-a chine is running.

From the foregoing 1t will'be seenthat when the machine is running the berries are continually subjected to a rubbing action against each other and against the blades of the members K, L and L so that the pulp is gradually removed from the berries and the latter are separated from the pulp and finally washed while passing -through; the

drum E in the tank F. The berries are'not liable to be injured during the rubbing action, as the berries are continually rolled over and fed forward in the several drums to prevent crushing of the berries. It will be noticed that by increasing or decreasing the tension of the several springs N, N N and N the berries can be retarded more or less in the several drums according to the .the tank F, as such light, defective berries do not drop down,but rise on the water to the level thereof and are removed by the use of a strainer.
